The long-awaited upgrade to NOAA's GFS model is up and running. It will be run in parallel to the old model for comparison until September.
"The U.S. government
is juicing up its weather
This week, the National Oceanic and Atmospheric Administration announced that it has upgraded its main weather
forecasting model, called the Global Forecast
"Virtually any aspect of the weather forecast
ó whether it is temperature or precipitation ó will see overall improvement with this upgrade," Brian Gross, director of the Environmental Modeling Center at the National Weather Service
, said during a conference call with reporters.
NOAA scientists say the new system will also be better at predicting major weather events
such as hurricanes by more accurately predicting a storm's path and intensity.
To make such improvements, NOAA's Global Forecast System is getting a new engine
, or "dynamical core
," called the Finite-Volume Cubed-Sphere."
